transferring the cans from thecooker 2 to the cooler'3, as is diagrammatically.illuse 'tratedat 10. The transfer means 9 andr10 7 may be of anysuitable or desirable construetion, .but are preferably of the form illustrated in my copending application filed April 18; 192 8,Serial No. 271,070. Theshell of the cooker, 1. is provided with amultion the conveyor 18 to permit the same to be moved-to the desired position to cause the ,cans to enter the shell of the cooker 1 through.

plicity ofopenings,11,.12, 13, 14, and 16,

' through which the cans to be heated'may be admitted'into, the cooker 1,. depending upon the time of cock desired. Thecans may be admitted intokany one of said openings, 11, 12, 13, 14, 15 01216 by'means of a slidably' mounted trough 17 which is slidably mounted any oneof the openings 11, 12, 13, 14, 15 or I v 16. The exactconstruction and mode of operation of this type ofmechanism isillustrated in -Iny copending. application .filed April 18, 1928, Serial No. 27 1,070.- 1 r WVhen itis'desired to subject the canned;

, goods to a.long-cook, the cans are admitted into the cookerl through the opening 11 and are transferred by. the, transfer means 9 .to the cooker 2.1and are then transferred by the transfer means 10 to the cooler 3. If

ashorter time of cook is required, in order to correctly process the canned goods, the

canned goods may be admitted to'any oneof the openings 12, '13, 14, 15 or 16, and 1 desired the cansmay be bypassed along the conveyor 18 by the cooker 2. directlyto1the cooler 3.- It willtherefore be obviousthat the canned goods may be subjected to. any

desired ftime of cook depending upon the inletqthrough which the'cans areadmit'ted into the cookerel and onwhether or'not the cannedgoodsare'caused to bypass the cooker lifted from position to permit the and 27, and asingle inlet 29. cooker 30Jmay be connected in the combina- The inlets 11, 12, 13,14, 15 and 1e are preferably formed at equally spaced intervals. alongthe shell ofthe cooker 1 so that if the cans are admitted into the cooker l through the inlet 11, the cooker 1 has a'capav city-of, forexample, 1500 cans. If the cans are admitted through the inlet 13, the cooker will have a capacity of, 1000 cans, and if the cans are admitted through'the inlets. 14, 15 V or '16, the cooker will-have a capacity of 750,

500 01 250 cans respectively. *The cooker 2 may likewise have a capacity of 1500 cans so any time'of cook may be had between the ranges of thecapacitiesof 250 and 3000 cans as desired,or required, in order to correctly process the canned goods without va'ryingthe speed at which the shafts 4, 5 and 6 of-the combined cooker and cooler are oper ated. i I 1 5 In the modified form of this invention i1- lustrated in Figure '2, 1 is combined with a cooker 2. and with a cooler 3 The cooker 1 may be provided only withan inlet'lland an outlet 22. The cooker 2" is provided with a multiplicity of outlets 23, 24 25 26 tion and each of the cookers 1 2* and may have a capacityof-lOOO cans, or-such' other capacity. asmay be desired. The track 18 is provided with slidablymounted chutes '17 and is arranged so that either the cookers l or 30 may be bypassed as'desired, depend- :ing upon the time of cook required in order to correctly process the-canned goods. For example, bybypassing the-cooker 1*" and admitting the cans intothe cooker 2 through the o ening 29*,any desiredftime of cook may. e had by taking thecans out of the cooker 2 through'any one of the openings 23* to27'respectively, giving acooker-capacity of from 200 to1000 cans, that is, by

bypassing'also the cooker 30. 'Acapacityof 1200 cansmay be had'by either passing the fcansthrough the cooker Pand then-intothe cooker 2 through the 'opening 29 andout through the'outlet 23', or bypassing thecans 1 into the cooker 2 through'the opemng '29 and out-the outlet 23 and then into the cooker 30; aIt will beobvious that'jany' desired 5 time of cook maybe-had in this combination of cookers and coolerwithin' a-rang'e of 11011120003118: to 3000 cansin' steps'of 200 cancapacities of the entire apparatus.
